POLE-HOISTER.

SPECIFICATION forming part of Letters Patent No. 763,969, dated July 5,1904.

Application filed October 1, 1902.

To all whom, it rim/y con/007771;

Be it known that I, GEORGE R. 'DoDD, a citizen of the United States,residing at Anderson, in the county of Anderson and State of SouthCarolina, have invented certain new and useful Improvements inPole-I-Ioisters, of which the following is a specification.

My invention relates to pole or timber hoisters, and is designed toraise telegraphpoles, timbers, iron beams, and the like in an easy andexpeditious manner.

In the drawings forming a part of this specification, and in which likesymbols of reference represent corresponding parts in the several views,Figure 1 is a side elevation of the device. Fig. 2 is a side view takenat right angles to Fig. 1. Fig. 3 is a view looking in an oppositedirection from that shown in Fig. 1. Fig. 1 is a'sectional view of amodified form, showing the pulleys at the sides of the pole instead of acentral pulley in the same. Fig. 5 is a sectional View similar to Fig. 1with a supplemental sleeve to lengthen the vertical rod. Fig. 6 is aview of a deadman or fork used in connection with the hoistingmechanism. Fig. '7 is a modified form of deadman, and Fig. 8 is a viewof adjustable truck used in transporting the device.

The main body of the device is formed of legs 1, set at an angle towardeach other and held in place by cross-pieces 2, back and front, andplates 3 on each side of the same. The usual bolts 1 or the like areprovided.

5 is the vertical rod, adapted to be raised and lowered in the mainframe by means ofa rope or the like 6, running over a barrel or Windlass'7. operated by a winch 8, and adapted to be locked by a pawl 9. Therope 6 passes over pulleys 10 and 11, journaled, respectively, in top ofone of the legs 1 and in bottom of rod 5, and is connected by a pin orjournal 12 tothe main frame.

13 is a deadman or fork formed of rods 14, connected by chains 15, saidchains being adjustable to conform to the work desired.

16 represents a modified form of deadman or fork; but my preferred formis the one generally used, as it has been found more ef ficient,conforming naturally to the inequalities of the ground upon which it isused.

$erin N 125,497. (No model.)

17 is a toothed fork at top of pole 5, the object of the same being toreceive the pole and hold the same thereon.

18 is a modified form of pole-receiver, being arc-shaped and having aspike 19 to take into the pole.

31 is a pin connecting rope 32 to the main frame, said rope passing overpulley 33.

20 represents pulleys located on each side of the pole 5, the same beingused. in lieu of pulley 33 when desired and having a plurality of ropes21 passing from the pin 31 to tongs 24. This form is used when thetimber 5 is of light construction and it is desired not to weaken thesame by forming a hole or housing in the same for the pulley 10.

In Fig. 5 I have shown a modified form of pole 5, the same having asleeve or the like 22, the object of the same being to lengthen orshorten the pole to conform to the particular work. Of course any numberof these sleeves may be used as desired.

23 represents supplemental or adjustable feet for the legs of thedevice, formed with longitudinal slots and connected by screwbolts, theobject of the same being to adjust the same to agree with theinequalities of the ground. I may also use similar feet on the deadmanor fork(shown in Fig. 7) and spikes at the base of the various legs andfeet.

241 is a pair of tongs or the like adapted to grip the pole in theinitial hoisting movement.

25 is a truck composed of wheels 26, sleeves 27, shaft 28, pins 29, andthumb-screws to lock the shaft and the sleeves.

The operation of the device is as follows: When it is desired to raisethe pole, the same is engaged by tongs 24, and the winch operated untilthe pole is raised sufficiently to place the deadman under the same. Thefork 17 is then placed under the pole and the winch again operated,raising the pole, and by manipulating the same as the pole is raised thesame may be placed in its desired position. When it is desired totransport the device, the same is placed on the truck 25, the legs 1engaging or reposingwithin the pins 29 and the legs 1 acting as thehandles of a pushcart. The sleeves and axle or shaft on the dead manpermit the same to adjust automatically to the width of the legs I. andthe thumb-screws 3U locking the device when inoperative.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. In a device of the character described, a main frame, a rod workingin the same, a ca ble passing beneath the top of the rod and adapted tobe operated by the same, and engaging means at the free end of the cableadapted to clutch the material to be lifted.

2. In a device of the character described, the combination with a mainframe, of a vertical rod working in the same, means for operating therod, a cable passing through the top of the rod and adapted to beoperated by the same, and adjustable feet for the legs of the mainframe.

3. In a device of the character described, a deadman composed of mainlegs connected by flexible bands, or the like.

4:. In a device of the character described,

the combination with the main frame, of a rod working in the same, acable connected to the frame and passing beneath the rod, a windlassconnected to the cable to operate the rod, a rope passing through therod and connected to the frame, and clamping means at the free end ofthe rope to grip the material.

5. In combination with a pole-hoistcr, an adjustable truck, the sameconstructed with a telescoping axle, screws to hold the parts whenadjusted, and pins upon the axle to re ceive the sides of thepole-hoister.

6. In a pole-hoister, the combination with the main frame, of avertical, rod working in the same, means for operating the rod, and aninsertible sleeve at the top of the rod to lengthen or shorten the same.

In testimony whereof I aflix my signature in presence of two witnesses.
